so I had two baby ducks and 6 baby chicks (all about 3 weeks old). Yesterday, one of the ducklings died. Ever since then I have noticed my Pekin duckling is panting (or so it looks) and making a weezing/heavy breathing sound. I don't think it's too hot, the brooder is about 80 degrees. The day before the duckling died, we let them explore outside and splash around in their little water tub. need advice =/ I love my duck.
